Are there any good resources and step by step tutorials on Simplex Noise? I have been Googling on it for a while now but I really can't find any good ones. I kinda understand the theory behind it but I have no clue how it works from A to Z and how to implement it.

(I am not looking for a library)

Why this is not a duplicate of this question

In this question I am asked how Simplex Noise works from A to Z, rather than how the coordinate system gets converted.

  • \$\begingroup\$ This looks promising: link. I haven't read it all, but as far as I can tell it describes a way of implementing perlin noise using OpenGL. Found on Google Scholar with query Perlin Noise. Also this one, from NVIDIA's GPU Gems 2. \$\endgroup\$ – Krienie Aug 18 '13 at 10:50
  • \$\begingroup\$ Those are resources on Perlin Noise rather than the new version Simplex Noise. \$\endgroup\$ – Jeroen Aug 18 '13 at 15:43
  • \$\begingroup\$ You might want to be more specific with what parts of if you still don't understand. \$\endgroup\$ – MichaelHouse Aug 18 '13 at 16:01
  • \$\begingroup\$ @Byte56 I understand nothing but that you use a grid of (D+1) and basically the visual theory behind it. I do not understand how to create, get and interpolate the noise. \$\endgroup\$ – Jeroen Aug 18 '13 at 16:02

    \$\begingroup\$ Stefan Gustavson's paper is still the best general reference to how simplex noise works from A to Z. I suggest you study that carefully, and then post a new question if there are parts of it you don't understand. \$\endgroup\$ – Nathan Reed Aug 18 '13 at 17:50
